UNITED STATES EDWARD M. ROSENFELD, OF CLEVELAND, OHIO` RADIATOR.

Application filed March 25, 1922.

To all whom t may concern.'

Be it known that I, Enwann M. RosnNr'nLn, a citizen of the United States residing at Cleveland, in the county of Cuyahoga, and

State of Ohio, have invented certain new and,

useful Improvements in Radiators, of'which the following is a specificatiomreference being had to the accompanying drawings.

This invention relates to improvements in radiatorsfand more particularly to improvements in automobile radiators.

An important object ofthe invention is to provide a radiatorof this type embodying removable sections so constructed that a single section may be removed for repair, replacement or the like and the radiator employed with the section removed.

A further object ofthe invention'is to provide a construction of this character whereby the removal of the sections is greatly facilitated. j 1

A still further object is to provide in a radiator an improvedA construction wherebyl assembly and repair of a'radiator is materially facilitated Without detract-ing from the appearance of the radiator; l 2

A still further object of the invention is to provide a device of this character which is simple in its construction, durable in service and a general improvement in the art.

These and other objects I attain by the construction and arrangement `shownin the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate likeparts throughout.

ReferringI now moreV particularly to the' drawings, the numerals 10 and 11 indicate Serial No. 548,744.

' upper and lower reservoirs and tanks each provided upon the adjacent faces thereof at the ends of such faces with depending flanges 12 to which are secured side members 13 for fmaintaining the reservoirs 10 and 11 in proper position. Each reservoir is likewise provided upon the'face thereof next adjacent the other reservoir with a flange 14 extending longitudinally of the inner edge thereof. The adjacent walls ofthe radiator. are provided with a series of spaced aligned openings 15, and the flanges 14 thereof are provided in alignment with these openings with pairs of spaced openings 16, the purpose of which will presently appear.

The numeral 17` indicates headers each comprising a shell having an enlarged portion 18 terminating in a restricted neck 19 provided with an outstanding flange 20, the opening of the neck corresponding in size to the openings 15 of the reservoirs 10 and 11 and being adapted for alignment with these openings, the fianges 2O engaging the metal of the reservoirs at the sides of the openings 15 with the Vinterposition of a gasket 21 having an opening corresponding in size to the openings of the neck and reservoir. Thev numeral 22 designates a U-shaped header attaching member, the arms 23 of which are bent at their ends to form the hook portions 24 which are adapted tovengage in pairs of openings 16. These arms receive therebetween the neck portions 19 of the headers and bear against' theflanges 2O ef these-neck portions.v The bight portions of theheader attaching plate are relatively widened and provided with openings 25 through which are directed headed securing elements 26 which engage in .threaded openings 27 formed in the reservoirs 10 and 11, these openings preferably beinaiformed in a ledge provided by pocketing the reservoirs, as at 27a, at the corners thereof and continuing the metal of the adjacent facesof-thereservoirs iny these pockets; A lock washer 28 is preferably disposed between .the head of the headed element 26 and the attaching plate 22 to prevent rotation ofthe securing members.

lThe 'numeral 29 indicates 'tube sections each comprising-a pluralityof tubes and formed byemploying a sheet of corrugated material andbending the salme longitudinally and securing thefree edges thereof together as by welding, as at 30,- the corrugations of the vplate combining to form alternate tubes 31 and dividing walls 32. The

numeral 33 designates yfins, each horizontally disposed and each provided with a plurality of openings 34 and each adapted for the reception of a tube unit 29, the openings being preferably six in number. These tube plates combine the tube units to form a radiation unit U, each iin or plate being secured to the tubes of this unit by soldering or the like. To the upper and lower ends of the tubes of each radiation unit U are secured plates 35 having openings 36 similar to the openings 34 of the plates 83 which receive the ends of the tube units 29 and which are welded thereto to form a tight joint. The

r. plates 35 are of such size that they will fit within the enlarged end 1S of the headers 17 and are welded thereto, as at 37. It will be seen that a plurality ofiadiation units are thus provided each comprising a pair of headers 17, one arranged at each end of the unit, and a plurality of tube units 29 maintained in spaced relation and subdivided longitudinally to provide cooling passages between the units by the plates 33.

When a radiation unit U becomes leaky for any reason, the same may be removed by removing the securing elements 26 of the Y header attaching members 22 thereof and the tube section removed from the radiator. If it is desired to employ the radiator while the tube section is removed gaskets 3S are applied to the openings 15 and plates 39 employed for covering the gaskets and maintained in position by the U-shaped header attaching members 22 in the same manner in which the headers 17 are maintained in position. These sections being exactly similar, -a new section may be inserted in lieu of an old section in but a few moments, it being unnecessary to separate the upper and .lower reservoirs to accomplish this object since the units U are free from portions projecting into or interlocking with the reservoirs 10 and 11.

In order to maintain the appearance of the radiator I provide cover plates 40 which are attached te the edges of the side members 13 adjacent the adjacent edges of the reservoirs at the front side of the radiator, the attachment being in the form of removable screws or the like so that the plates may be readily removed for access to the header attaching plates 22. These plates are preferably provided with scallops 41 closing the ends of the pockets 27:L and giving the solid portion of the front of the radiator a smooth unbroken appearance.

From the foregoing it is believed to be obvious that a radiator constructed in accordance with my invention is particularly well adapted for the use for which it is in tended by reason of the fact that a radiation unit may be removed and the radiator employed when so desired, and by reason of the fact that the replacement or removal of a section may be accomplished with the loss of but a few moments time and without removing the radiator from the car since the units are removable from the front face of the radiator. It will furthermore be ob vious that the construction hereinbefore set forth is capable of some change and Inediication Wit-Iwut'materially Ideparting from the spirit of my invention and I accordingly do not limit myself to such construction except as hereinafter claimed.

I claim:

1. In a radiator, upper and lower reservoirs provided in adjacent faces with aligned opposed openings, removable radiation units provided at the ends thereof with headers having openings in their ends alignable with aligned openings of the reservoirs, and means carried by the reservoirs and movable longitudinally of' the headers for clamping the headers in position.

2. In a radiator, upper and lower reservoirs provided in adjacent faces with aligned Openings, removable radiation units provided atthe ends thereof with headers having openings alignable with aligned openings of the reservoirs, means for clamping the headers in posi-tion including flanges formed on the adjacent faces of said reservoirs and provided with pairs of openings aligned with the openings of the faces, U- shaped clamping members having the arms vthereof engaged in relatively restricted portions of the headers, the ends of the arms being disposed in `the pair of openings of the flange corresponding to the opening with which the header is aligned, and means,

extending through the bight portion of the U-shaped member for forcing the same toward the adjacent reservoir section.

. 3. In a radiator, upper and lower reservoirs provided in adjacent faces with 'opposed openings, removable radiation units provided at the ends thereof with headers having openings alignable with aligned openings of the reservoirs, means for clamping the headers in position including flanges formed on the adjacent faces of the reservoirs at corresponding sides 0f the openings thereof and having openings formed therein, and members embracing the headers and having portions engaged in the flange openings and other portions having a connection with the adjacent reservoir at the opposite side of the openings thereof whereby they may be adjusted toward the reservoir to clamp the header thereagainst. f

4. In a radiator, upper and lower reservoirs provided in adjacent faces with aligned openings, removable radiation units -provided at the ends thereof with headers having openings alignable with aligned oper ings of the reservoirs, means for clamping the headers in position including restricted neck portions formed on said headers and provided at their upper ends with flanges, substantially U-shaped clampin members receiving the neck portions of t e headers and abutting the outer faces of the flanges thereof, flanges formed on said reservoirs and having openings in which the ends of the arms of the U-shaped members are disposed, and means engaging the bight portions of the U-shaped members and the adjacent reservoirs ,for forcing sucfh bight portions toward the reservoirs whereby to clamp the headers against the reservoirs.

5. In a radiator, a reservoir provided in a face thereof with an opening and at the edge of Such face with a fiange having openings formed therein, a radiation unit em- 'bodying a header having an opening adapted to coact with the opening of the reservoir and provided at the sides of the opening with an outstanding flange, a U-shaped clamp engaging beneath the iange of the header and having its ends engaged in the openings of the flange of the reservoir, and means extending through the bight portion of the clamp and engaging the reservoir for forcing such bighi-l portion toward the reservoir.

In testimony whereof I hereunto aix my signature.
